First SLI Enable Problem

Guys,

So I've just installed a second GTX260 card, both BFG 260GTX MC55 OC. My nvidia control panel does show the option to enable SLI and it seems to be taking ages? Is this normal?

F.Y.I I hit the buttom at 22:45 and it's been saying 'Applying Changes' and nothing else 'seems' to be happening?

Any ideas or shared experience?

Regards,

Adam.
 
Hi,

Stupid question, but did you uninstall the Nvidia Graphics driver before you installed the spare card?

Also, does your copy of Windows see the two cards in Device Manager?

If you have not done the first, unsinstall old driver and reinstall the newest driver from Nvidia site.

Hope this helps.

Cheers

Von
 
Sorry should have been more specific. Have Gigabyte X58 with the SLI stamp on and using the SLI bridge that came with it.
Have removed all drivers from the system with Driver Sweep and performed a fresh install of the 266.xx drivers from nvidia.

Have then gone into nvidia control panel... 'Set SLI & PhsyX Config', selected 'Maximise 3D Performance. Selected 'Auto Select' for PhsyX and hit apply.

How long should it take?
 
I've seen posts on this forum saying not to use Driver Sweeper as it can mess things up.

Can you do a system restore to before you ran Driver Sweeper?

I would have thought if you fitted the second card the drivers would be automatically installed as you already have them on your system.
 
Shouldn't take more than 30 seconds tops.

Also not a fan of driver sweep and similiar - they seem to cause more problems than they solve with nVidia drivers lately - try rolling back to before you ran driver sweep if possible and then reinstalling the latest nVidia drivers with the "clean" setting enabled.
 
I take it you've switched system restore off.

Not a good idea before making any big changes.

Reinstalling Windows should sort it all out :eek:

Unless anyone's got any better ideas?

You could try uninstalling all the Nvidia drivers (I use CCleaner), deleting the Nvidia folder on your C drive, Running CCleaner to clear out defunct registry entries and then doing a clean installation of the Nvidia drivers.
 
So your system doesn't work at all now?

Try it with just one of the graphics cards installed.

If that doesn't work try starting it in safe mode. Hopefully you can uninstall the drivers etc. from there.

Perhaps you should test the new card. If it's knackered that may be the cause of your problems.
 
no no I meant I'm doing a fresh windows... fortunatly there isn't anything on the system as yet.
Both cards tested and working.

It'll be fine ;)

Just keep away from Driver Sweeper.

If you have both cards fitted then when you install the Nvidia drivers they should be installed at the same time.

Just make sure you get the correct drivers from the Nvidia website for your operating system and graphics cards.
 
You are using an i7 CPU rather than a xeon? seen 2-3 times people having trouble enabling SLI when using xeons on X58 boards.
